1 Claim.

This invention relates to an antiglare device for head lamps, the general object of the invention being toprovide a perforated metal plate which bears against the inner face of the lens of the head lampl and theplate constructed and arranged that it will prevent the rays of light from the lamp from blindingjdrivers of other cars.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts to be herenafter fully described, illustrated in the accompanying drawing and specically pointed ont in the appended claim.

In describing the invention in detail, reference will be had to the accompanying drawing wherein like characters denote like or corresponding parts throughout the several views, and in which:

Figure 1 is a view looking toward the device when placed in a head lamp.

Figure 2 is a fragmentary portion of the device enlarged to show how the perforations are punched therein. v

Figure 3 is an elevation of the head lamp with parts in section showing how thefsame is arranged therein. t

As shownin this drawing the device A is formed of a metal plate lof a shape to t in the front end Iof the head lamp L directly in rear of the transparent member 2 of the lamp, the metal plate being provided with the bent ears 3 which t over the front end of the lamp casing and is held in place by the rim 4 which holds the transparent member 2 in place. Of course, the mem- 35' ber can be held in place in any other suitable manner. The metal plate is punched by a square punch to form the projections 5 and, of course, these projections extend from one face and form recesses in the other face and in punching the metal a four-point star-shaped opening 6 is formed in the metal. The projections extend outwardly and engage the inner face of the transparent member as clearly shown in Figure 3. The member I has its lower part cut on a straight edge as shown at 8 and this is spaced above the lower part of the lamp so that rays can pass under the member I without being eiected thereby. However, the other rays must pass through ing in Width to' the holes 6 and they prevent the rays of light coming from the lamp from blinding drivers of other cars orv vehicles approaching the vehicle device will prevent the rays of head lamps from blinding other light from the drivers and yet will notinterferewith the proper illumination of the road by the lamps.

It is thought from the foregoing description invention will be readily apparent.

It is to be understood thatchanges may be made in the construction and in the combination and arrangement of the several parts provided lappended claim.

Having described the invention, what is claimed as new is:

Avnonglare attachment for a head lamp comprising a metal plate having four-sided projections `of hollow construction extending from one face thereof with the spaces formed by the projections opening out through the other face, the sides of each projection sloping inwardly and forwardly and each side being of triangular shape and lsaid sides of each projection being slightly spaced apart with the spaces gradually increasand means for holding the small end of the projection the plate in a head lamp with the said iront ends of the projections engaging the inner face of the transparent member 40 of the lamp, the inner face of the plate and the inner walls of the projections being reiective,k

the bottom of the plate being straight and spaced from the lower part of the lamp to form a space at the lower part of the transparent member uncovered by the plate,
